z/VSE V3.1 exploitation of IBM eServer zSeries technology

SCSI disks attached to zSeries FCP channels (CHPID type FCP):
IBM zSeries Fibre
Channel Protocol (FCP) channels are designed to allow customers to attach industry-standard Small
Computer System Interface (SCSI) devices. A typical topology might consist of one or more FCP
channels, a switch (such as the IBM 2109), and a controller with one or more ports and one or more
SCSI devices. FCP channels are FICON Express or FICON Express2 cards that have been personalized
with the FCP feature.

The objective of z/VSE SCSI disk support is to offer clients more storage choices as well as help
lower Total Cost of Ownership (TCO).

z/VSE is designed to attach selected SCSI disks in addition to Extended Count-Key-Data (ECKD) and
Fixed Block Architecture (FBA) disks. Only SCSI disks that are contained within the IBM
TotalStorage Enterprise Storage Server Model F20, 800, and 800 Turbo are qualified for
z/VSE V3.1 at this time. Qualification of DS8000 and DS6000 series SCSI disks is planned for a
later date.

z/VSE SCSI-FCP support is designed to be transparent to z/VSE components and subsystems, vendor
interfaces, and user-written programs. z/VSE SCSI-FCP support includes both operating system
components and files containing user data. Note: This is an addition to the
April 7, 2004, preview, which said that z/VSE SCSI-FCP support would apply to user data
only.

With the appropriate features and service applied to the IBM zSeries server, it is possible to IPL z/VSE from a SCSI disk.
Therefore, it is possible to build a "SCSI-only" z/VSE system. Some limitations apply to a
SCSI-only system. For example, a stand-alone dump cannot be created on a SCSI disk and dump
information cannot be written to SCSI disks.

z/VSE V3.1 is designed to support SCSI disk volume sizes from 8 MB to 24 GB. Because z/VSE
itself uses the first 4 MB for internal purposes, the available user space is equal to the defined
size of the disk, minus 4 MB. z/VSE V3.1 limits VSE/VSAM to the first 16 GB of any SCSI
volume. VSE/VSAM limitations for ECKD disks are unchanged in z/VSE V3.1. That is, although
z/VSE V3.1 supports 3390 ECKD volumes of up to 32,760 cylinders, VSE/VSAM is restricted to the
first 10,017 cylinders (approximately 4.5 GB).

z/VSE SCSI-FCP support includes multipathing. Multipathing is a means to increase the availability
of the device. A lock file can be assigned to a SCSI-FCP disk using z/VSE DASD sharing.

z/VSE V3.1 does not support FlashCopy® for SCSI-FCP disks.

Special migration considerations apply. It is not possible to use the Fast Service Upgrade (FSU)
process to move from a VSE/ESA V2.6 or V2.7 system to a z/VSE V3.1 system with SCSI system
residence disks. VSE/VSAM Backup/Restore is only possible from SCSI to SCSI (or ECKD to ECKD). You
must use the Import/Export utility to move VSE/VSAM data from ECKD to SCSI disks. Similar
restrictions apply to FBA to SCSI migration. Refer to the
z/VSE Planning Guide
for more details.

z/VSE SCSI-FCP disk support complements SCSI support in z/VM Version 5 and Linux for zSeries.

The individual z/VSE maximum SCSI volume size limits do not apply to z/VM minidisks backed by SCSI
disks. When operating as a guest under z/VM (using SCSI disks not directly attached to z/VSE), z/VM
presents SCSI disks as 9336-20 FBA disks. In this case, z/VSE sees them as FBA, not CSI, disks.
The maximum z/VSE V3.1 FBA volume is 2 GB. Of course, multiple 2 GB minidisks can be assigned
within the limits of a single physical SCSI disk volume controlled by z/VM. For SCSI disks directly
attached to z/VSE under z/VM, the normal z/VSE limits described above apply.

Open Systems Adapter-Express2 10 Gigabit Ethernet (OSA-Express2 10 GbE):
OSA-Express2 represents a new generation of zSeries LAN adapters. It is available as an
optional feature exclusively on z890 and z990 servers. OSA-Express2 can help satisfy the network
bandwidth requirements of your applications. The OSA-Express2 10 GbE feature supports QDIO mode
(CHPID type OSD) only with full duplex operations. For z/VSE 3.1 and TCP/IP for VSE/ESA, the
feature is compatible with OSA-Express2 GbE and OSA-Express.

Support for OSA-Express2 10 GbE is available in VSE/ESA Version 2 Release 6 and later.

OSA-Express2 Gigabit Ethernet (OSA-Express2 GbE):
OSA-Express2 is available as an optional feature exclusively on z890 and z990 servers. The
OSA-Express2 GbE feature supports QDIO mode (CHPID type OSD) only with full duplex operations. For
z/VSE 3.1 and TCP/IP for VSE/ESA, the feature is compatible with OSA-Express.

z/VSE 3.1 supports the capability of up to 640 TCP/IP stacks or connections per dedicated CHPID, or
640 total stacks across multiple LPARs using a shared or spanned CHPID on a single OSA-Express2
feature on the z890 or z990.

Support for OSA-Express2 GbE is available in VSE/ESA Version 2 Release 6 and later.

HiperSockets, including HiperSockets Spanned Channels:
With HiperSockets, TCP/IP traffic travels between LPARs and virtual servers at near memory
speed, rather than network speed. Spanned Channels allow z/VSE to use HiperSockets that link LPARs
or virtual servers using different Logical Channel Subsystems (LCSSs).

Support for HiperSockets, including HiperSockets Spanned Channels, is available in VSE/ESA
Version 2 Release 7 and later.

Spanned external channels:
Spanned external channels can be shared among LPARs across multiple Logical Channel Subsystems
(LCSSs). A z/VSE image in a single LPAR can use FICON Express2, FICON Express, OSA-Express2, and
OSA-Express adapters defined across multiple LCSSs.

Support for Spanned External Channels is available in VSE/ESA Version 2 Release 7 and
later.

Adapter interruptions:
Adapter interruptions are exclusive to z890 and z990 servers. High performance adapter
interrupt handling first introduced with HiperSockets is also available for OSA-Express2 and
OSA-Express in QDIO mode (CHPID type OSD), as well as FICON Express2 and FICON Express (CHPID type
FCP). This zSeries advance provides a more efficient technique for handling I/O interrupts and is
designed to reduce path lengths and overhead in both the operating system and the adapter.

Adapter interruptions for CHPID=OSD are supported in VSE/ESA Version 2 Release 7 and
later.

Adapter interruptions for CHPID=FCP are supported in z/VSE Version 3 Release 1.

OSA-Express Integrated Console Controller (OSA-ICC, CHPID type OSC):
OSA-ICC is available exclusively on z890 and z990 servers. It is designed to eliminate the
need for a non-SNA 3174 controller, and may replace existing 3174 or 2074 controllers. 3270
emulation for console session connections is integrated into one of the ports of an optional
OSA-Express 1000BASE-T feature. It supports TN3270E and Non-SNA DFT 3270. OSA-ICC support may help
reduce TCO and aid infrastructure simplification.

Support for OSA-ICC is available in VSE/ESA Version 2 Release 6 and later.

FICON Express2 and FICON Express:
FICON channels allow higher I/O bandwidth compared to ESCON® channels. FICON Express2 is a
technology refresh that offers four ports per feature and the potential for increased performance.
FICON Express2 is exclusive to z890 and z990 servers.

CP Assist for Cryptographic Function (CPACF):
CPACF is available exclusively on each and every central processor (CP) within a z890 or z990
complex. It provides an "on processor" function designed to accelerate symmetric cryptographic
operations. The function is delivered through a new set of zSeries architecture instructions.
CPACF is a no-charge hardware feature.

Support for the PCICA feature is available in VSE/ESA Version 2 Release 7 and later.

Crypto Express2:
Crypto Express2 is available as an optional feature exclusively on z890 and z990 servers. It
is designed to offer the functions of both PCICA (supported by VSE/ESA V2.7 and later) and
PCIXCC (not supported by any VSE, including z/VSE) cards. When functioning as a PCICA card, the
Crypto Express2 feature provides compute-intensive RSA cryptographic operations to reduce CP usage
and increase SSL throughput.

Support for Crypto Express2 will be available as a PTF in VSE/ESA Version 2 Release 7 and
later.

Up to 30 LPARs:
Support for up to 30 LPARs is available exclusively on IBM zSeries 890 and 990 servers. More LPARs provide additional
configuration flexibility.

Support for up to 30 LPARs is available in VSE/ESA Version 2 Release 6 and later.

Up to four Logical Channel Subsystems (LCSSs):
With multiple LCSSs, z890 and z990 servers can attach more than 256 internal and external
channels. However, any single instance of z/VSE remains limited to 256 channels. Additional LCSSs
are available exclusively on IBM zSeries 890 and 990 servers. The z890 supports up to two LCSSs, and the z990
supports up to four LCSSs.

Support for up to four LCSSs is available in VSE/ESA Version 2 Release 6 and later.

z/VSE V3.1 exploitation of IBM TotalStorage technology

IBM TotalStorage 3494 Virtual Tape Server:
The IBM TotalStorage 3494 Virtual Tape Server (3494 VTS) is designed to help reduce operating
costs and improve overall tape library processing performance. The subsystem writes virtual 3490E
volumes to a tape volume cache on a high-speed RAID disk buffer to help improve performance. It
then stacks the virtual volumes on high-capacity 3592 or 3590 cartridges. IBM 3494 VTS can help
reduce batch processing time, TCO, and management cost. A single 3494 VTS can be shared across
multiple platforms, including IBM zSeries, pSeries®, and xSeries®, as well as various non-IBM platforms.

Improved support for IBM TotalStorage 3494 Tape Library:
The IBM TotalStorage 3494 Tape Library System (3494 Tape Library) is designed to provide
reliable, granular, scalable tape automation. It addresses data retention and business continuity
requirements. The 3494 Tape Library supports 3490E, 3590, and 3592 tape drives with high-capacity
or short-length rewritable media, as well as 3592 WORM media. A single 3494 Tape Library can be
shared across multiple platforms, including IBM zSeries, pSeries, iSeries, and xSeries, as well as various non-IBM
platforms. New native support in z/VSE V3.1 allows the 3494 Tape Library to be supported
through the S/390 channel command interface, mainly Perform Subsystem Function (PSF) and Perform
Library Function (PLF) commands. z/VSE tape library support includes IBM TotalStorage 3592 tape
drives.

Existing LCDD (native VSE) and VGS (VSE as a VM guest) 3494 Tape Library support is based on the
XPCC/APPC communication protocol. The new z/VSE V3.1 support is easier to use and more
extendable than the existing 3494 Tape Library support. For compatibility reasons, the older LCDD
and VGS interfaces are unchanged and will be retained along with the z/VSE V3.1 support.
However, the LCDD support will not be enhanced. For example, LCDD support does not include 3592
tape drives. Neither the new nor old support includes export/import function.

z/VSE V3.1 support for the 3494 Tape Library is best used together with a tape management
system from the independent software vendor of your choice.

IBM TotalStorage 3592 Enterprise Tape Drive:
The IBM TotalStorage 3592 Enterprise Tape Drive J1A (3592) is designed to address needs of
applications for high capacity, fast access to data, and/or long-term data retention. The 3592
offers both 300 GB (up to 900 GB with 3:1 compression) and 60 GB cartridges. Either cartridge type
is available in rewritable or WORM (
W
rite
O
nce
R
ead
M
any) formats. WORM cartridges are designed to provide nonalterable, nonrewritable tape media for
long-term records retention. When the 3592 detects a WORM cartridge, the tape drive prevents
overwrite or changes to existing customer data. New data can be appended to existing data until the
capacity of the cartridge is reached.

VSE/ESA V2.6 and later support the 3592 as a channel-attached tape drive. z/VSE also supports
the 3592 as a tape component of a 3494 Tape Library.

The IBM TotalStorage ESS offers 3380 and 3390 (including 3390 "Large Volumes" with up to 32K
cylinders) ECKD format. The ESS is designed to support a broad range of operating environments
including IBM zSeries,
pSeries, iSeries, and xSeries as well as several non-IBM systems.

Improved FlashCopy support for IBM TotalStorage ESS:
IBM TotalStorage FlashCopy technology is a point-in-time copy capability that can be used to
help reduce planned application outages caused by backups and other data-copy activities. FlashCopy
is designed to enable data to be copied in the background, then make both source and copied data
available to users almost immediately.

z/VSE V3.1 adds support for the NOCOPY option for greater efficiency in copying from disk to
tape. The NOCOPY function can be used to copy the data directly from the source to tape without the
need to first copy all of the physical data to an intermediate backup copy.

FlashCopy Version 2 support for IBM TotalStorage ESS:
FlashCopy Version 2 (V2) includes the features of FlashCopy (including NOCOPY), plus
extensions designed to improve capacity management and disk utilization. It offers functions that
improve business efficiency and performance.

z/VSE V3.1 supports the following selected FlashCopy V2 functions:

Dataset Copy
offers a new level of granularity. It allows more efficient use of disk capacity. It can also
reduce background completion times because FlashCopy no longer needs to be performed at the volume
level when only a dataset copy is required. With Dataset Copy, the source and target volumes may be
different sizes. It also allows the copied data to reside at a different location in the source and
target volumes. Note: Because a VSAM "dataset" is a complex entity consisting of a catalog and one
or more data extents, VSAM files are not candidates for the Dataset Copy function.

Elimination of LSS constraint
can help simplify administration and capacity planning for FlashCopy. Source and target volumes
can now span logical subsystems within a storage server.

Multiple Relationship FlashCopy
offers new flexibility. It allows up to 12 target volumes to be created from one source volume in
a single FlashCopy operation. Multiple target volumes can be used for testing, backup, and other
applications.

Performance improvements
in FlashCopy V2 are designed to reduce the time required to complete a FlashCopy establish command.

z/VSE V3.1 does not support these FlashCopy functions:
Incremental FlashCopy, Consistency Group commands
, and
Inband Commands over a Remote Mirror link
.

Peer-to-Peer Remote Copy Version 2 support for IBM TotalStorage ESS:
IBM TotalStorage Peer-to-Peer Remote Copy (PPRC) technology allows businesses to automatically
replicate data at a remote site using ESS PPRC and PPRC V2 functions. PPRC includes a synchronous
data-mirroring technique designed to constantly maintain a current copy of the local application
data at a remote site. PPRC V2 offers all the functions of PPRC, but with extended distances.
These functions provide the ability to keep local and remote copies in synch and ready for a quick
switchover should a disaster occur.

VSE/ESA V2.7 and later support PPRC and PPRC V2 through the ICKDSF component.

The DS8100 is a dual 2-way system based on IBM's POWER5 technology. It offers 16 GB to 128 GB of
processor memory (disk cache). It offers 1.1 TB to 38.4 TB of RAID 5 or RAID 10 disk capacity in a
single frame, and up to 115.2 TB with an expansion frame.

The DS8300 is a dual 4-way system based on IBM's POWER5 technology. It offers 32 GB to 256 GB of
processor memory (disk cache). It offers 1.1 TB to 38.4 TB of RAID 5 or RAID 10 disk capacity in a
single frame, and up to 192 TB with two expansion frames.

The DS8000 series packs more capacity into each enclosure than the previous generation of IBM
storage units. The result is a disk system that occupies up to 20% less floor space than the ESS
800. The DS8000 is designed to accommodate growth. The architecture is designed to scale up to 1
petabyte of storage. A petabyte is equal to 1000 terabytes, or a million gigabytes.

The IBM TotalStorage DS8000 series offers 3380 and 3390 ECKD format. The DS8000 series is designed
to support a broad range of operating environments, including IBM zSeries, pSeries, iSeries, and xSeries as well as several
non-IBM systems.

zSeries attachment is via ESCON, FICON, or FCP channels. S/390 attachment is via ESCON or FICON
channels. VSE/ESA V2.7 and later support ESCON and FICON attachment and ECKD disk formats.

IBM TotalStorage DS6000 series:
The IBM TotalStorage DS6000 series is designed to deliver enterprise-class storage capabilities
in a low-cost, space-efficient, modular package. The high performance and advanced functions found
in enterprise disk storage devices are now available in a 19-inch rack mountable package that's just
5.25 inches high. As your needs grow, you can add capacity with modular expansion units of the same
size. The DS6800 has a dual active controller with an integrated PowerPC® RAID controller. It
offers 4 GB cache. Capacity ranges from 584 GB to 4.8 TB of RAID 5 or RAID 10 storage in a single
unit. With optional DS6000 expansion enclosures, the maximum capacity is 67 TB.

The IBM TotalStorage DS6000 series offers 3380 and 3390 ECKD format. The DS6000 series is designed
to support a broad range of operating environments, including IBM zSeries, pSeries, iSeries, and xSeries as well as several
non-IBM systems.

FlashCopy support for IBM TotalStorage DS8000 and DS6000 series:
IBM TotalStorage DS8000 series and DS6000 series make no distinction between FlashCopy and
FlashCopy V2. The features of FlashCopy V2 are included in a single FlashCopy Feature (PTC 
Point in Time Copy) for DS8000 series and DS6000 series storage servers.

VSE/ESA V2.7 and later support FlashCopy, although only z/VSE V3.1 supports NOCOPY and the
FlashCopy V2 functions listed above.

Remote Mirroring for IBM TotalStorage DS8000 and DS6000 series:
The IBM TotalStorage DS family introduces new terminology. The ESS PPRC V2 capabilities are
included in a new Remote Mirror and Copy Feature (RMC) for DS8000 series and DS6000 series storage
servers.

VSE/ESA V2.7 and later support RMC Metro Mirror, Global Copy, and Global Mirror modes through
the ICKDSF component.

z/VSE Version 3 Release 1 component changes

Improvements have been made to these component products.

Note that z/VSE is the successor to IBM's VSE/ESA product and that many products and functions
supported on z/VSE may continue to use VSE/ESA in their product names.

VSE Central Functions Version 7:
To simplify ordering, packaging, installation, and service, Language Environment for VSE/ESA
(LE/VSE) is now a standard component of VSE Central Functions V7. LE/VSE no longer exists as a
separate product. A number of enhancements have been incorporated into LE/VSE to address
user-submitted requirements, usability, and z/OS® affinity issues. For example, there are
improvements to storage issues and messages, the ability to monitor LE/VSE GETVIS usage, enhanced
LSTQ, and improved trace and problem determination. In addition, LE/VSE offers improved
internationalization with more locales, code page converters, and enhanced Euro support. OLPD will
also gather debug information in case of an LE abnormal termination. LE information is stored into
the problem determination file IESPRB and can be displayed using the "Online Problem Determination"
dialog of the Interactive Interface. Refer to the
z/VSE Planning Guide
for more details.

IBM High Level Assembler for z/OS, z/VM, and z/VSE V1.5 (HLASM):
A new release of HLASM replaces IBM High Level Assembler for MVS, VM, and VSE V1.4. In
addition, a new release of the productivity-enhancing HLASM Toolkit is available as an optional
feature. Refer to Software Announcement
204-122
, dated June 8, 2004, for more details.

CICS® Transaction Server for VSE/ESA V1.1.1 (CICS TS for VSE/ESA):
There is no change to CICS Transaction Server for VSE/ESA V1.1.1. As part of the
investment protection strategy of z/VSE V3.1, IBM will continue to ship CICS/VSE® V2.3 along
with CICS Transaction Server for VSE/ESA V1.1.1 at no additional charge.

MQSeries® for VSE V2.1.2 enhancements:
Due to the ongoing development of the MQSeries for VSE product, new functions have been added
and z/OS affinity has been enhanced. z/VSE customers can now take advantage of the following new
features:

MQSeries-CICS bridge
is now available with MQSeries for VSE V2.1.2. The MQSeries-CICS bridge enables an application,
not running in a CICS environment, to run a program or transaction on CICS and get a response back.
This non-CICS application can be run from any environment that has access to an MQSeries network
that encompasses MQSeries for VSE.

Extended system administration
is available using online CICS panels, PCF, MQSC, and to a limited extent the MQINQ and MQSET MQI
calls. Historically, MQ/VSE has supported administration through these means for common MQ
attributes. This support has now been expanded to cover an extended range of common and MQ/VSE
specific attributes, so that nearly all MQ/VSE system attributes can be controlled or examined by
local or remote administrative applications.

Extended MQI function
now supports syncpoint control of the MQGET, MQPUT, and MQPUT1 MQI calls. By default, these MQI
calls put and get messages within a single unit of work. Application programs can now use the
MQGMO_NO_SYNCPOINT and MQPMO_NO_SYNCPOINT options to isolate message I/O from their current unit of
work.

Message transmission
between MQSeries queue managers involves protocol-specific operations to transmit data. When
transmitting large messages, the number of these operations can be reduced by transmitting larger
units of data. As a performance improvement, MQSeries for VSE now supports transmission buffers for
TCP/IP channels up to 64K.

The MQSeries for VSE Redbook
, first published in 1999, has been republished with major updates to all chapters, including new
sections and chapters on enhancements to the product introduced over the past four years. The order
number for the new Redbook is SG24-5647-01.

MQSeries for VSE V2.1.2 runs on VSE/ESA V2.6 or later.

z/VSE Version 3 Release 1 operating system improvements

Basic operating system improvements are often driven by customer-submitted requirements.
z/VSE V3.1 addresses many of these requirements. This section cannot cover each and every
improvement. A few examples are described below. Refer to the
z/VSE Planning Guide
for additional improvements as well as more information on those shown below.

Interoperability:
z/VSE plans to continue to advance the focus on interoperability that began with VSE/ESA
Version 2 Release 5, and continued with VSE/ESA Version 2 Release 6 and VSE/ESA
Version 2 Release 7. VSE Java-based connectors now support JDK 1.4.

Current information and code updates for VSE connectors can be found on the VSE Web site at

VTAPE enhancements:
New tape format options have been added to the remote VSE Virtual
Tape (VTAPE) server. They include:

Zipped ASWTAPE (.zip)  One or more tape images can be included in one
PKZIP file to save space and transfer time for the remote server.

Binary PTF data (.ptf)  This format simulates a PTF tape out of the
data (binary job stream) you get when ordering PTFs electronically. The
simulated tape can be used directly with the PTF apply dialogs.

Zipped PTF data  PTF data can also reside in a ZIP file.

These new tape formats are available in VSE/ESA Version 2
Release 7 and later. In addition, a host name can now be provided
in place of an IP address for the VTAPE start command.

New predefined Environment C:
Real storage is relatively plentiful on zSeries servers and larger
VSIZEs are practical. Given today's resources, predefined Environment B
is no longer adequate in many cases. A new large environment was needed
to take advantage of additional resources. A new large predefined
environment (Environment C) has been created with a VSIZE of 2 GB. This
new environment may fit into 2 GB of real storage and run without paging.
It is defined with 120 partitions, including 108 dynamic partitions.
Maximum partition size is defined to be 512 MB. For initial
installation, a 2 GB page dataset is used and allocated on DOSRES. This
requires a systems residence device at least the size of a 3390-3. If
the appropriate page dataset is provided on a separate volume, or if the
real storage is large enough so that paging does not occur, space on
DOSRES may not be required.

VSE/POWER enhancements:
When migrating existing VSE/ESA V2.7 VSE/POWER queue/data files
to z/VSE V3.1, they need not be reformatted during a cold start.
They can be migrated during a VSE/POWER warm start. The lengthy process
of backing up the spool file to tape, reformatting the disk, and
reloading the files from tape is no longer required. The VSE/POWER
queue/data files must be at the VSE/ESA V2.7 level.

A VSE/POWER data file can now be extended by "n" extents during a single
VSE/POWER warm start without any interruption of the spooling process.
Formatting of data file extents no longer costs an extended amount of
time when existing data files must be enlarged, or when
pre-VSE/ESA V2.7 spool files are imported to z/VSE V3.1.

WTOR security:
Applications can now ask the operator for secure information (such
as a password) without it showing on the console. Like z/OS, the WTOR
Macro now supports routing code 9 so that the actual response text is not
displayed on the console or on the hardcopy file.

JCL enhancements:
Systems logical units (SYSRDR, SYSIPT, SYSLST, and SYSPCH) can be
assigned to disk in a dynamic partition. Prior to z/VSE V3.1,
systems logical units could only be assigned to disk in static
partitions.

Librarian enhancements:
A DATE operand has been implemented to control the setting of time
stamps in the library, sublibrary, and member descriptors for the LIBR
commands COPY and MOVE. The DATE parameter has the same format and
function as the DATE parameter in the RESTORE command.

A SORT operand has been added for the LIBR command LISTDIR SDL to specify
how the SVA Phases are to be sorted in the output. By default the output
is sorted by Phase name. If SORT=ADDRESS is specified, the phases are
sorted by their location in the SVA. Partition GETVIS is used to sort
the SDL by address.

SDAID enhancements:
The SDAID wrap buffer has been enlarged to 256 KB and moved to the
31-bit SVA area. This decreases the likelihood that a re-IPL may be
required as a result of a complex trace. It also provides some 24-bit
virtual storage constraint relief. A new trace type has been added to
track LOCKING and UNLOCKING of resources.

Section 508 of the U.S. Rehabilitation Act

z/VSE V3.1 is capable as of March 4, 2005, when used in accordance with IBM's
associated documentation, of satisfying the applicable requirements of Section 508 of the
Rehabilitation Act, provided that any assistive technology used with the product properly
interoperates with it. Note that IBM assumes that Section 508 applies only to normal and routine
end-user operations, and not to setup and service functions.

Beginning with VSE/ESA Version 2 Release 5, a key element of the VSE strategy has been to
help customers
protect
their extensive investments in core VSE applications, data, and IT skills, as well as business
processes and end-user training. A second important objective is to help
integrate
VSE into the overall network. A third major element of the VSE strategy is to help enable clients
to implement new on demand solutions in a three-tier, hybrid environment that
extend
and leverage existing VSE information assets.

Exploiting interoperability between VSE and any Java-capable platform, clients may be able to
simplify their IT infrastructure. In turn, infrastructure simplification may help reduce cost,
disruption, and risk. It may help increase productivity and lessen time-to-market for new, on
demand solutions.

Integrated hybrid solutions may consist of a zSeries running z/VSE plus the user's choice of any
Java-capable server. For example, because integration is based on industry and open standards, the
middle tier platform may be any IBM or equivalent.

zSeries (the same or a different server with z/OS or Linux)

pSeries (AIX® or Linux)

xSeries (Windows or Linux)

iSeries (OS/400® or Linux)

z/VSE is designed for VSE clients with growth opportunities. "Growth" may be generated by some
combination of:

This powerful and flexible model, perhaps implemented using innovating IBM technology such as:

IBM zSeries 890 server and

IBM TotalStorage SCSI-FCP disk storage

may provide a compelling solution for both growth-oriented and cost-conscious VSE clients.

z/VSE can execute in 31-bit mode only. It does not implement z/Architecture, and specifically does
not implement 64-bit mode capabilities. z/VSE is designed to exploit selected features of IBM
zSeries hardware.

Hardware requirements

z/VSE V3.1 support for IBM zSeries 890, zSeries 990, zSeries 800, zSeries 900, or equivalent 64-bit servers will
be in 31-bit mode, in LPAR, or under z/VM V4, or later.

Specifically, z/VSE V3.1 does not support 64-bit real or virtual addresses. Therefore z/VM,
with its support for 64-bit real and virtual (allowing 64-bit virtual machines such as Linux for
zSeries and z/OS) addressing, is a compelling option for most VSE customers using zSeries servers.

Support for S/390 Parallel Enterprise Server Generation 5 and 6, S/390 Multiprise 3000, or
equivalent 31-bit servers is in basic mode, in LPAR, or under z/VM V4, or later.

Software requirements

For z/VSE V3.1 customers using VM, z/VM V4, or later, is required to exploit state-of-the-art
IBM virtualization technology for one or more of the following reasons:

Multiple VSE production, development, or test images

Both VSE and Linux on zSeries

Both VSE and z/OS during a z/OS migration transition period

Both VSE and z/OS on a permanent basis

z/VM V4.1, or later, is required by customers planning to use z/VM in combination with Integrated
Facility for Linux (IFL), or who want the affordability advantages of engine-based pricing offered
by International Program License Agreement (IPLA) Terms and Conditions.

To use HiperSockets for high-speed interoperability between z/VSE V3.1 and Linux on zSeries,
corresponding Linux exploitation is required. Linux on zSeries is not provided by IBM. Linux must
be obtained from distributors. For the most current information on Linux distributors, refer to:

z/VSE can execute in 31-bit mode only. It does not implement
z/Architecture, and specifically does not implement 64-bit mode
capabilities. z/VSE is designed to exploit selected features of IBM
zSeries hardware.

IBM 9345 Disks are not supported as system or data devices.

Programs running on VSE/ESA Version 2 Release 7 using official
interfaces will be able to run unchanged with z/VSE V3.1.

There is a Fast Service Upgrade (FSU) path from VSE/ESA Version 2
Release 6 and VSE/ESA Version 2 Release 7 only. It is not
possible to use the FSU process to move from a VSE/ESA V2.6 or V2.7
system to a z/VSE V3.1 system with SCSI system residence disks.

Limitations:
Limitations in using z/VSE V3.1 are:

z/VSE V3.1 is designed to support SCSI disk volume sizes from 8 MB
to 24 GB. Because z/VSE itself uses the first 4 MB for internal
purposes, the available user space is equal to the defined size of the
disk, minus 4 MB. z/VSE V3.1 limits VSE/VSAM to the first 16 GB of
any SCSI volume.

VSE/VSAM limitations for ECKD disks are unchanged in z/VSE V3.1
compared to VSE/ESA Version 2 Release 7. That is, although
z/VSE Version 3 Release 1 supports 3390 ECKD volumes of up to
32,760 cylinders, VSE/VSAM is restricted to just the first 10,017
cylinders (approximately 4.5 GB).

z/VSE V3.1 does not support FlashCopy® for SCSI-FCP disks.

When operating as a guest under z/VM (using SCSI disks not directly
attached to z/VSE), z/VM presents SCSI disks as 9336-20 FBA disks. In
this case, z/VSE V3.1 sees them as FBA, not SCSI disks. The maximum
z/VSE V3.1 FBA volume is 2 GB.

User programs cannot use SCSI commands directly.

VSE/VSAM Backup/Restore is possible only from SCSI to SCSI (or ECKD to
ECKD). You must use the Import/Export utility to move VSE/VSAM data from
ECKD to SCSI disks.

Performance considerations:
The overall performance of z/VSE V3.1 depends on the individual
hardware and software components and on the specific environment and
setup parameters.

Resource consumption:
In general, the overall CPU requirement of z/VSE V3.1 is
similar to that of VSE/ESA Version 2 Release 7. This applies
as long as the same environment is used (for example, Batch or CICS TS
for VSE/ESA V1.1.1) without exploitation of new functions. Actual
customer experience may vary.

(SC33-6601) for important configuration instructions, and should note
that
product access keys from IBM and Connectivity Systems are different and
are not interchangeable.

DB2 Server for VSE and VM Version 7 Release 4:
DB2 Server for VSE and VM uses an access/usage protection method
that requires a password key to enable the software function.

The password key will be generated and delivered automatically from IBM
accordingly whenever an order is placed for DB2 Server for VSE and VM.

ACF/VTAM for VSE/ESA Version 4 Release 2:
ACF/VTAM for VSE/ESA V4.2 uses an access/usage protection
method that requires a password key to enable the software function. The
following types may be ordered:
